*Estimated average solids during filling of containment area. Drying/desiccation to truckable solids may be several months **The costs for the mechanical process vary by equipment type, size and vendor. The individual pieces of equipment are not to be used alone. They are used in part of a process depending on the Integrated System designed for the specific sediment that is being dewatered. Individual vendors rental price is based on the type of equipment and duration needed. Most vendors requested project specifications in order to quote a price.
